Purpose

This webpage/report is intended to aggregate information from different agencies (i.e. USACE, SFWMD, FWC, USGS and NOAA) into one spot to help inform local government agencies and stakeholders on conditions within Lake Okeechobee, the Caloosahatchee River and Estuary and Coastal southwest Florida. The data provided here should be considered preliminary and are subject to change.

Lake Flows: In the past 7 days the total outflow from Lake Okeechobee was 159 AF with 0 AF to the Caloosahatchee through S-77, 127 AF through S-310 in Clewiston, and 0 AF to the EAA through S-351, S-352, and S-354. The total net inflow to the Lake was 53,879 AF (50,370 AF from Fisheating Creek, S-71, S-72,S-84s, S-65EX, and S-65EX1) with a total backflow volume of 3,509 AF from C10A. Water conservation areas received flows of 9,832 AF, 10,669 AF, and 20,412 AF at WCA1, WCA2, and WCA3, respectively. Everglades National Park received 22,364 AF.
